I know I'm NOT politically correct and that the stupid law profession may not agree, BUT, should we really care if execution has some element of pain? I'm sure the criminals all caused plenty of pain during their crime, and it isn't a deterrant, it's punishment! So who cares? I say Hang 'em high! Lets bring back Judge Roy Bean! Nuts to long delays and multiple appeals. Sentence the criminal today and hang 'em at Noon tomorrow in the town square of the jurisdiction where they committed their crime.
Now THAT would be meaningful Death Penalty reform!
